If two bad blocks occur on two member drives of an array, the integrity of the stored data is endangered. Media Scan, Infortrend's innovative intelligent drive handling function, retrieves data from the damaged sectors. Media Scan handles low quality drives in both the degraded mode and during the rebuild process. For additional data security, other intelligent drive management features include the transparent resetting of hung hard drives, power-failure management, and bad-drive handling during LD expansion.

The Task Scheduler is combined with Media Scan so that the scanning operation can be scheduled beginning at a specified start time and repeating at the configurable intervals. The operation is thus hands free. Each such schedule can be defined to operate on individual hard drives, all drives of a certain class, all member drives of a specified logical drive, or all member drives of all logical drives.
